> Key: HDFS-11976
> URL: https://issues.apache.org/jira/browse/HDFS-11976
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Yongjun Zhang
>
> If exception X is thrown in try block, and exception Y is thrown is finally
> block, X will be swallowed.
> In addition, finally block is used to ensure resources are released properly
> in general. If we throw exception from there, some resources may be leaked.
> So it's not recommended to throw exception in the finally block
> I caught one today and reported HDFS-11794, creating this jira as a master
> one to catch other similar cases.
> Hope there is some static analyzer to find all.
